    摘要: The invention relates to a converter comprising resonant circuit elements (S1, S2) for chopping a DC voltage (U1), in which switch-on phases of the circuit elements (S1, S2) are alternating, and comprising a circuit assembly (5) with resonant circuit elements (Cr, Lr) which is used for processing the chopped DC voltage (U3) and for producing an output voltage (U2). As a type of converter load monitoring that can be changed with the least possible circuit expenditure and the least possible measuring losses, there is proposed to compare in a dead time phase (Ttot) before a circuit element is switched on the voltage (US1) or (US2) applied to the circuit element with a threshold (Uth) and ascertain from this comparison result whether an inductive or capacitive converter load is present. As a second embodiment there is proposed to determine during a dead time phase (Ttot) the derived value (dUS1/dt) of the voltage (US1) present on the circuit element and ascertain with the determined derived value (dUS1/dt) whether an inductive or capacitive converter load is present.

    摘要: The invention relates to a method of regulating the power supply for two or more power consumers, wherein at least two of the power consumers are connected to a direct-voltage source (1) via at least a respective voltage regulator (21a, 21b, 22, ... 2n) and wherein each voltage regulator (21a, 21b, 22, ...2n) is supplied with an input voltage (Uin,a, Uin,1b, Uin,2, ..., Uin,n) by the direct-voltage source (1) and supplies one of the power consumers with a steady voltage (Uout,1a, Uout,1b, Uout,2, ... Uout,n). In order to optimize the voltage supply and to avoid high power losses and heat losses, it is proposed that a) for each voltage regulator (21a, 21b, 22, ... 2n) a control signal is generated that is dependent at least on the applied input voltage (Uin,1a, Uin,1b, Uin,2, ... Uin,n) and on a specific reference value (Vref,1a, Vref,1b, Vref,2, ..., Vref,n) for the voltage regulator (21a, 21b, 22, ... 2n) and b) the input voltages (Uin,1a, Uin,1b, Uin,2, ... Uin,n) are regulated by the direct-voltage source (1) as a function of at least one of the generated control signals.

    摘要: A conversion circuit for converting solar power into an alternating 3-phase maims (M) comprises a converter (conv) for converting the power from a solar cell (sc) into an unipolar converter output voltage provided between a first and a second converter output terminal of the converter, the converter having a constant power output regulation. The conversion circuit further comprises an inverter (Inv) for cyclically switching one of 3 3-phase output terminals to the first converter output terminal, one to the second converter output terminal and one intermittently to the first and second converter output terminal. With this conversion circuit and method, high capacity energy storage components (such as a capacitor having a large capacitance) can be avoided in the conversion circuit.

    摘要: The invention relates to a transformer (10, 10') with a core (11) which has a center piece (11a) with a first and a second flange (11b, 11c), in which a first and a second winding (12, 13) of the transformer (10, 10') are wound on the center piece (11a). To produce a transformer as compact as possible which allows simple adaptation to limit leakage currents, it is proposed that the winding end pieces (12a, 12b) of the first winding (12) guided out of the winding body are guided through at least one recess in the first flange (11b) and that winding end pieces (15a, 15b) of the second winding (13) guided out of the winding body are provided which form at least partly loose line ends. Alternatively, the winding end pieces (12a, 12b) of the first winding (12) guided out of the winding body are guided immediately about the edge of the first flange (11b) and connected with connecting elements (14a, 14b) which are arranged on the side of the first flange (11b) opposite the center piece (11a).

    摘要: A buck converter, boost converter or flyback converter is generally represented as a two-port having a primary side with a primary switching device (10; 38; 70; 98; 110), and a secondary side with a secondary switching device (20; 50; 80; 106). The primary switching device is controlled in such a way that the on-time is adapted to the voltage at the primary side of the converter. The relation between the on-time of the primary switching device and the primary voltage is a generally hyperbolic function.
